Convert 3.9 yards to inches.
Answer:
140.4 inches
Step-by-step explanation:
there are 36 inches in a yard
3.9 times 36 is 140.4
Hope It Helps
Sorry If I'm Wrong
3.9 yards is equal to 140.4 inches.
We have,
The concept used to convert 3.9 yards to inches is the conversion factor between yards and inches. The conversion factor states that 1 yard is equal to 36 inches.
By multiplying the given value in yards (3.9 yards) by the conversion factor (36 inches/yard), we can convert the measurement from yards to inches.
This concept of using a conversion factor allows us to convert between different units of measurement.
To convert 3.9 yards to inches, we can use the fact that 1 yard is equal to 36 inches.
So, to convert 3.9 yards to inches, we multiply 3.9 by 36:
3.9 yards * 36 inches/yard = 140.4 inches
Therefore,
3.9 yards is equal to 140.4 inches.

One pygmy shrew weighs 3 3/18 ounces, and another weighs 4 4/7 ounces. Estimate the total weight.
O about 8 1/2
O about 7 1/2
O about 9 ounces
O about 7 ounces
==============================================
Reason:
It might help to draw a number line for this.
3/18 is closer to 0 than it is to 1/2 = 9/18, so the mixed number 3 & 3/18 rounds to 3 when rounding to the nearest half.
4/7 is closer to 1/2 = 4/8 than it is to either 0 or 1, so 4 & 4/7 rounds to 4 & 1/2 when rounding to the nearest half.
Adding 3 to 4 & 1/2 gets 7 & 1/2 since we add the whole parts 3+4 = 7, and the fractional part stays as it is.
-----------
Check:
(3 + 3/18) + (4 + 4/7) = 7.738 approximately
7 + 1/2 = 7.5 exactly
The two results aren't too far off. The estimate of 7 & 1/2 is an underestimate.
Answer:
About 7 1/2 ounces
Step-by-step explanation:
Add your whole numbers first, 3 + 4 = 7
Now the fractions:
3/18 = 1/6
Estimate 4/7 + 1/6, the answer is somewhere between 1/2 and 1 whole. Therefore the answer is about 7 1/2
Check:
3/18 × 7/7 = 21/126
4/7 × 18/18 = 72/126
21/126 + 72/126 = 93/126
The actual answer is 7 31/42, so the closest answer is 7 1/2

assume that you are trying to use the inverse tangent function on your calculator to find the angle of a vector in the x-y plane.
The tangent of the angle formed when x = 0 is undefined.
However, the angle described by when x = 0 are;
E) Either 90° or 270°
Which method can be used to find the measure of the required angle?
The question appears to be incomplete. The possible other part of the question is as follows;
When x = 0, and the calculator is used to find the tangent, the calculator indicates that the value is undefined, such that the calculator will not be able to give the value of the angle that corresponds with a value of x = 0.
What must the angle in degrees be when x = 0
Solution;
[tex]tan( \theta) = \frac{ \Delta y}{\Delta x} = \frac{y - value}{x - value} [/tex]
When x = 0, we have;
[tex]tan( \theta) = \frac{y - value}{0} = \infty [/tex]
However, when x = 0, the terminal side have rotated from the initial side to the positive or negative side of the ordinate, which corresponds to 90° or 270°, which are located on the ordinate of the graph
The correct option is therefore;
E) Either 90° or 270°

When using the inverse tangent function on a calculator to find the angle of a vector in the x-y plane, it is important to understand the limitations and considerations involved. The inverse tangent function, commonly denoted as arctan or atan, returns the angle whose tangent is a given value. However, special attention should be given to the range of the output and the quadrant of the angle. Additionally, some calculators have a two-argument inverse tangent function that considers both the x and y components of the vector, providing a more accurate result. To find the angle of a vector in the x-y plane using the inverse tangent function on a calculator, we typically use the atan or arctan function. The function takes a single argument, which is the ratio of the y-coordinate to the x-coordinate of the vector. It returns the angle in radians whose tangent is equal to that ratio. However, it's important to consider the limitations of the inverse tangent function. The output of the function is typically in the range of -π/2 to π/2 (-90 degrees to 90 degrees). This means that the function can only provide angles within this range. If the vector falls in the second or third quadrant (where the x-coordinate is negative), the function will return an angle between -90 degrees and 90 degrees. To obtain the correct angle in these cases, we need to add or subtract 180 degrees, depending on the quadrant. Some calculators also have a two-argument inverse tangent function, often denoted as atan2 or arctan2. This function takes both the x and y components of the vector as arguments. It provides a more accurate result by considering the signs of both components and the quadrant of the angle. This eliminates the need for additional calculations to determine the correct quadrant. In conclusion, when using the inverse tangent function on a calculator to find the angle of a vector in the x-y plane, we should be aware of the range of the output and the quadrant in which the vector lies. For more accurate results, it is recommended to use the two-argument inverse tangent function (such as atan2 or arctan2) if available on the calculator, as it handles the quadrant determination automatically.

What is quadratic simple?Quadratics are polynomial equations of the second degree, which means they have at least one squared term. It is also known as quadratic equations. The quadratic equation has the general form: ax2 + bx + c = 0.
So, how are quadratic functions significant?Quadratic functions occupy a distinctive place in the school curriculum. They are functions whose values are easily estimated from input values, therefore they are a modest improvement over linear functions and provide a major shift away from attachment to straight lines.
According to the given information:Given (5x + 6)(3x - 6) = 0
Using the zero factor principle: if ab = 0 then a = 0 and b = 0
So,
(5x + 6) = 0 or (3x - 6) = 0
for the (5x + 6):
(5x + 6) = 0 (subtracting both side by 6)
5x + 6 - 6 = 0- 6
so, x = -(6/5)
Same calculation for (3x - 6) = 0 we get x = 2

Equation and solution of equation :
17.25 + p(17.50) = 69.75
17.25 + 17.50p = 69.75
17.50x = 69.75 - 17.25
17.50p = 52.50
p = 52.50/17.50
p = 3

The area that occupies on a plan drawn to the given scale is 0.024 m²
Given,
The area of the playing surface at the Olympics stadium in Beijing = 3/5 hectare
The scale factor on a plan drawn = 1:500
We have to find the area that occupies on a plan drawn to the given scale:
Applied to the area we consider k² as the area is the product of two dimensions.
So, k = 1/500
Now the area on plan:
a : k² = actual area
a : (1/500)² = (3/5) × 10000
a : (1/250000) = 3 × 2000
a × 250000 = 6000

What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In item 18, we have that when x = 2, y = 1, hence the constant is:
k = y/x = 1/2 = 0.5.
Hence the equation is:
y = 0.5x.
In item 22, we have that when x = -5, y = 2, hence the constant is:
k = y/x = -2/5 = -0.4.

We are aware that the formula A-1 = (adj A) / can be used to get the inverse of a matrix A. Here, the denominator contains det A, which is the determinant of A. We are aware that a fraction with a denominator of 0 is not defined. Since det A = 0, A-1 is not defined. In other words, a single matrix's inverse is not defined.
